[0028] Example:
[0029] like Figure 1 to Figure 7 As shown, the present invention provides a novel pediatric clinical medicine doser, comprising a mounting shell 101, a drug storage cartridge 401 connected by a support assembly is arranged in the mounting shell 101, and one side of the mounting shell 101 is provided with a through- The measuring cylinders 103 are installed on the two sets of fixing racks 102. The measuring cylinders 103 are made of transparent material. A scale line 105 is provided on one side of the measuring cylinders 103. 501 is provided with a first one-way valve 504, and the bottom of the measuring cylinder 103 is provided with a second one-way valve 104.
[0030] When the medicine doser is in use, a larger volume of medicinal liquid can be stored in the storage cartridge 401. Since the storage cartridge 401 is connected with the measuring cylinder 103, the medicinal liquid can be entered into the measuring cylinder 103 through the first one-way valve 504 first. After metering, the metered medicine flows out through the second one-way valve 104, so as to avoid the situation of inaccurate weight caused by simply controlling the one-way valve for weighting.
[0031] The measuring cylinder 103 is provided with an installation frame 106 , two ends of the crank handle 701 are respectively rotatably connected to both sides of the installation frame 106 , and one end of the crank handle 701 is provided with a lifting gear 707 connected by a speed change assembly. There is a piston plate 601, a lifting gear 707 meshes with a rack 602 on the piston plate 601, a mounting plate 801 fixed with bolts is arranged at the inner bottom of the mounting frame 106, a threaded barrel 802 is arranged on the mounting plate 801, and a screw is arranged in the threaded barrel 802. A threaded rod 803 is connected, one end of the threaded rod 803 is provided with an adjusting wheel 805, and the other end is rotatably connected to a limit ring 804.
[0032]In the initial state, the piston plate 601 is at the bottom end of the measuring cylinder 103. Before the medicine is weighed, the threaded rod 803 can be rotated and moved linearly up and down in the threaded cylinder 802 by rotating the adjusting wheel 805. The threaded rod 803 moves up and down. During the process, the limit ring 804 is moved up and down, and then the limit ring 804 can be moved to an appropriate position according to the volume of the required component. After the position of the limit ring 804 is adjusted and fixed, the crank handle 701 can be shaken downward, and the crank handle 701 drives the lifting gear 707 to rotate to lift the rack 602 during the movement, and then drives the piston plate 601 to move upward to make the metering. Negative pressure is formed in the cylinder 103, and the medicine in the storage cylinder 401 is extracted into the measuring cylinder 103. Since the piston plate 601 is limited by the limit ring 804, the volume of the medicinal liquid extracted into the measuring cylinder 103 each time is With a fixed value, the liquid medicine can flow out from the second one-way valve 104 by shaking the crank handle 701 upwards. It is only necessary to repeatedly shake the shaking handle 701 to quickly measure a large amount of medicinal liquid, and the weight is relatively accurate and the practical value is high.
[0033] The medicine doser is also relatively convenient to clean. Just add clean water to the medicine storage cartridge 401, and then shake the crank handle 701 repeatedly to clean the medicine storage cartridge 401, the medicine delivery tube 501 and the measuring cylinder 103 at the same time, which is convenient for different The medicine is dosed, which improves the applicability of the device.
[0034] like figure 2 , 5 , 7, the speed change assembly includes a transmission gear 702 fixedly arranged at one end of the crank handle 701, a first support seat 603 and two sets of second support seats 703 are arranged in the installation frame 106, and the first support seat 603 is provided with a pass through The first speed change gear 604 and the second speed change gear 605 are connected by the shaft, the first speed change gear 604 and the second speed change gear 605 are fixedly connected by the shaft, and the two sets of the second support bases 703 are both provided with a reversing shaft 704. Gear 705, the transmission gear 702 meshes with the first speed change gear 604, the second speed change gear 605 and one set of reversing gears 705 mesh with the other set of reversing gears 705, and the lifting gear 707 is connected to one end of one set of rotating shafts 704 Rod 706 makes the connection.
[0035] During the process of shaking the crank handle 701 downward, the transmission gear 702 is driven to rotate clockwise, thereby driving the second transmission gear 605 to rotate rapidly through the meshing with the first transmission gear 604. During the rotation, the second transmission gear 605 passes through one of the The set of reversing gears 705 controls the other set of reversing gears 705 to rotate more quickly, so as to drive the lifting gear 707 to rotate to lift the rack 602 , and the control of the rack 602 is relatively fast, which effectively improves the efficiency of medicine dosage.
